The course design and synthesis with lab aims to provide the student:
1. a methodological approach to the design and carrying out of an organic synthesis
2. The basic principles and issues of the retrosynthetic analysis
3. The main reactions that are currently used in organic synthesis with particular emphasis on the mechanistic and stereochemical aspects.
Within the synthetic plan, the student must be able to recognize the principal reagents, to recognize and to explain the different types of reactions and their mechanism, propose possible synthetic routes for obtaining simple compounds.
In the laboratory, students will refine manual skills acquired in previous courses, work independently, be able to solve the real problems of organic synthesis and relate the experimental aspects of the concepts learned in the theoretical part.

Teaching Methods

The lessons will be lectures with projection of slides; the content of each slide will be presented in detail and discussed. The teacher will ask questions to push students to participate actively to the lesson, to formulate hypotheses and to propose possible solutions to the problems considered . With regard to the lab, students will make the experience in group, but in any case the work will be conducted, from the beginning to the end of the synthesis, in an independent way as much as possible. The teacher will help the students only when, after repeated attempts, they won’t manage to find the solution. The teacher will ask the students to consider the meaning of the operations performed and to reconnect them to the concepts examined in the theoretical part.

Lectures: 32 hours- laboratory activities: 24 hours. Laboratory performed with groups of two, maximum 3 students. Practical execution carried out by each student

Verification of learning

Report of the laboratory activity.
The final exam will be an oral dissertation where the student will be required to enucleate his lab experiences, explain basis concepts faced during the course. The student will be required not to keep in mind the concepts but to be able to explain fundamental concepts and the involved reactions. The student, in fact, will show the retrosynthetic processes by exploiting the slides used by the teacher during his course.
